Hermione believed that she had healed from the Battle of Hogwarts. She moved into a comfortable cottage with thick gardens and a warmth hearth. She began working at a bookstore and has plans to someday own it. However, she feels that something is missing. After meeting up with Ginny, she learns that her friends are struggling. Wanting a chance to spend more time alone together, Ginny and Harry ask Hermione if she would be willing to look after James, Albus, and Lily for the summer. Hermione happily agrees. What Hermione assumes to be a nice summer with her nephews and niece, soon gets turned upside down. She learns that Draco's son Scorpius and Albus are best friends. Her peaceful summer is soon changed when she realizes that she will have to come to terms with her past with Draco. Being forced into Harry's inner circle had never been part of Draco's plan. While he's pleasantly surprised by Harry's alarmingly forgiving nature, he doesn't expect to receive the same treatment from Hermione. When he learns that Hermione will be watching Harry's kids for the summer, he attempts to dissuade Scorpius and Albus from hanging out. However, the boys have other plans.
